Bruce, you are not alone and there are no simple solutions. It really all comes back to the institution and the stance they want to take. As an instructor you need the support of your administration to control such matters. One line of thought is to work with your instructional design team and come up with useful mobile tools that make the most use of such technology in the classroom. While another line of thought would suggest working with your administration to enforce some level of (zero tolerance rule) and gives you the empowerment to ask students to leave the class that do not follow classroom procedures. I have seen both of these techniques result in success but the bottom line is the support you will get from your administration. If anyone else has other ideas or comments, please share. James Jackson
